9 Claims.

This invention relates to steam radiators and has particularly to do with a portable radiator electrically heated wherein a small quantity of water is provided in the radiator to form steam for giving oil? heat to the radiator and the surrounding atmosphere.

An example of this type of radiator is found in Patent No. 1,852,252 dated April 5, 1932, wherein the operation and the uses of the radiator are clearly set forth.

It is an object of the present invention to provide an improved steam radiator design which may be manufactured at a lower cost and assembled with less difliculty than previously designed radiators. The result is a radiator which is just as serviceable as the old type and which is lighter and easier to handle. Another object of the invention is to provide a construction in which the radiator unit and the heating unit may each be constructed separately and later assembled into one unit. In order to accomplish this result it has been necessary to make considerable changes in the heating unit and what is called the boiler unit which consists of the tube surrounding the heating unit.

The design of the radiator has also been changed so that it may be constructed from a number of identical stampings and a passageway provided therein to receiverthe complete heating unit.

Other objects and features of the improved design will be brought out in the following description and claims.

In the drawings:

Fig. l is a side elevation of the radiator showing one section cut away.

Fig. 2 is an end view of the radiator.

Fig. 3 is an enlarged partial vertical section through one end of the radiator and combined heating unit.

Fig. 4 is an enlarged partial vertical section through the other end of the radiator and heating unit.

Fig. 5 is a section taken on the lines 5-5 of Figs. l and 4.

Referring to the drawings, the radiator portion of the steam radiator is composed of a series of identical stampings indicated at I0. These stampings are each formed with a flange and each of them has a protrusion I2 and a protrusion I3, as shown. A complete section of the radiator which is formed of a plurality of sections is composed of two stampings |0 placed together face to face andhaving the flanges |I radiator is then formed by uniting complete sections at the protrusions |2 and I3, this being also done by welding or brazing or other similar metal joining operations. Each of the protrusions |2 are provided with openings so that there is a continuous passageway through the top portion of the radiator. At each end the protrusions |2a and |2b are provided with an air valve I4 and a safety popoff valve I5 respectively. The joining protrusions I3 at the lower portion of the sections are each to be provided with an elongated aperture I6 having substantially the shape shown in Fig. 5. This aperture need not be provided in the end protrusion I3b to the right of the radiator, as shown in Fig. 1.

The heating unit of the radiator is to consist mainly of two concentric tubes 20 and 2|. The inner tube 20 is to extend substantially the length of the radiator and is adapted to house an electric heating unit. This tube 20 is sealed at one end as shown in Fig. 4, by a cap 22. At the other end of the tube 2D is a plate 23 which forms a seal with the tube 20 and which has a shape substantially the same as, but larger than, the apertures |6. The hole at the left end of the tube 20 is closed by an insulator 24 in which are 1ocated conducting tubes 25 leading to heating elef ments 26 stretched through the tube and spaced therefrom by insulators 21. Lead wires 25a. and heating elements 26 are fastened to the tubes 25 by being inserted into the tubes which are thereafter crushed on the wires.

Concentric with tube 20 is tube 2| which may be designed as a boiler tube. This tube 2| is provided at its lower portion with spaced holes \28 which permit water to pass from the lower portion of the radiator up to the heating unit. In the top portion of the boiler tube 2| are provided short vertical outlet tubes 29 which are so spaced on the boiler tube that each one falls about the center portion of a radiator section. These short tubes 29 may be termed feed or steam tubes since they direct steam or feed steam from the feeding tube 2| up into the sections of the radiator. f

Referring for a moment to the dimensions of the various elements, the diameter of tube 2| plus the length of tubes 29 must be substantially equal to the length of aperture I6. It is 'preferable that the aperture I6 have a length slightly greater than the length of the tubes 29 plus the diameter of the tube 2|.

In the assembly of the heating unit within the radiator section, a spacing cap 30 is iirst welded sealed together by a welding operation. The 55 over a round aperture 3| in the protrusion |3b.

plenishment of the water which is contained in the closed radiator and also allows for draining in case such is desired. After the cap 30 is welded to the radiator section, the tubes 20 and 2l may pass into the horizontal passageway which is provided in the lower portion of the radiator by reason of the apertures i6 and the joining protrusions i3. Since the apertures l are elongated the boiler tube 2l will pass into the radiator and after the tube 2li is located within the spaced member 82 and the end of .the tube 2l is positioned within the cap 3G, the plate 23, wihch is sealed to the tube 2li, will close the aperture l5 in the protrusion i3d. This plate may be sealed over this aperture by welding or other metal joining process and with this operation the entire radiator will be sealed. Suitable means 35 may be provided at the left end of tube 2l (see Fig. 3) to space the tube from the heating unit tube 2B. After the sealing of the plate 23 a second end cap 3@ may be placed over the insulator 2d to protect the same. 'I'his cap 3S is preferably provided with apertures such as 3l to permit ventilation and the cap t6 is preferably screwed to the radiator so that it may be removed. The heating unit within the tube 2li is removable so that the same may be replaced if this becomes necessary.

In order that the radiator may have support, stampings 38 (Fig. 2) may be fastened to the end sections by welding or other means. For example, as shown in Figs. 3 and 4, the stamping 38 at the right end of the radiator is fastened to the cap 3U and the protrusion i327. At the left end of the radiator stamping 33 is fastened the cap 36 and the protrusion 83a.

It will thus been seen that a complete radiator formed of similar sections may be manufactured, and the heating unit along with the boiler tube may be assembled therewith as an independent unit. 'I'his removes thev necessity of forming a radiator of two sections as in the patent previously mentioned and I have found that the provision of the feed tubes 29 furnishes sulcient outlet of steam which is formed in the boiler tube 2l. Steam is directed upwardly in sections and will rise of its own accord to the top of the sections. In case there is condensation at the top, the condensate will form on the sides of the sections and fall back to the lower portion of the radiator where there will again be heating. The air valve i4 is a standard type of valve as is common on most radiators of today and the popo valve l5 is provided to relieve the radiator of abnormal pressures which might possibly be formed thereon. The valve I5 is a standard valve and may be termed a safety valve.
